I went and got a p8p67 pro today and i5 2400 with 4 sticks of RAM. I installed everything into my old machine swaping out the old MB CPU and RAM. It's conected with a 750 TX PSU. When I boot it up I get 2 red lights on my MB one of them being CPU Led and the other I think is memok but I'm not real sure. The fans spin for about half a second then stop and computer turns off. I'm not sure how to fix this as I hardly know anything about building computers so any information would be helpful before I take it to a repair center so the can overcharge me to fix it.
